A foreign material control programme is a procedure implemented to prevent, detect and investigate instances of physical contamination in any facility that processes or manufactures food.
As the food industry becomes increasingly globalised with each passing year, supply chains become more complex. This expansive global network of agriculture, processing, production, transport and consumption is necessary to feed the growing world population, but the continuous expansion of the food supply chain also harbours an increased risk of physical contamination. As food products pass through multiple facilities, undergo a myriad of processing stages are handled by multiple people, there are more opportunities for foreign objects to contaminate the foods. A foreign material control programme is a means of mitigating the risk that physical contaminants pose to consumers, as well as to production processes and company reputation.
The global interdependencies of the food industry are complex: whether in production, logistics or sales.
The prevention and early detection of foreign material contaminants is also important as a means of improving the environmental sustainability of the entire food supply chain. By immediately eliminating contaminated foods from the production cycle, no excess resources are spent in processing or transporting them further. Additionally, undetected contaminants may proliferate and contaminate an even higher volume of food as they move through the production cycle. For these reasons, foreign material control programmes play an supporting role in reducing industrial food waste.
All internationally recognised food safety standards are based upon HACCP – a methodology in which potential sources of food safety hazards are identified and assessed in order to establish a procedure for proactively controlling for and reducing risk. Because foreign materials are one of the most common types of contaminants, food safety audits from certifying organisations invariably involve assessing the protocol by which a facility prevents, detects and investigates instances of physical contamination.
A robust foreign material control programme is thus a requirement for food safety certification according to DIN EN ISO 22000, IFS, BRCGS, SQF, FSSC 22000 and more. Though the exact requirements for HACCP-based control measures differ between these standards, each stipulates that methods for preventing and detecting physical contaminants must be validated and verified in order to ensure efficacy.
Here are some of the requirements regarding HACCP-based foreign material controls from internationally recognised food safety standards:
BRCGS – Foreign material hazards are considered during the hazard analysis (2.7.2) and documented risk assessment (220.127.116.11), as well as during assessment of the equipment maintenance programme (4.7.2) and cleaning protocols (4.11.3). The BRCGS Standard also includes an entire subchapter outlining the effective use of foreign body detection and removal equipment (4.10).
IFS – Foreign body management is outlined in section 4.12 and is considered a “knock-out” requirement for which non-fulfilment results in non-certification. In the IFS Foreign Body Management guideline, foreign body management is regarded as “directly related” to six distinct IFS food requirements: quality and food safety management, resource management, food defence, senior management responsibility, planning and production process, as well as ongoing measurements, analyses and improvements.
In addition to protocol and technologies designed to prevent contamination, an HACCP-based foreign material control programme must also include methods for detecting physical contaminants in food products. Contaminant detection equipment can serve as a critical control point in food processing facilities. The three most common types of contaminant detection equipment used in the food industry are:
Most foreign material detection technologies are outfitted with a product ejection system that can reliably isolate the contaminated product from the process flow.
Furthermore, advanced contaminant detection technology is equipped with software that generates and stores data about the batches it inspects and all instances of contamination. These capabilities facilitate traceability and detailed record-keeping, both of which are requirements for verifying the efficacy of a foreign material control programme.
According to major food standards, detection equipment must also undergo regular maintenance and calibration checks to ensure reliable performance.

A robust foreign material control programme is essential to ensure consumer health and safety. But even beyond the ethical imperative of food safety, effective foreign material controls can reap a number of benefits for food industry businesses.
All companies in the food industry should exhibit a
sincere commitment to consumer health and safety. Upholding this commitment
requires food industry businesses to take seriously the implementation and
execution of validated food safety processes, including foreign material
controls. But an effective foreign material control programme can do more for a
company than simply prevent a public relations crisis. Technology and procedure
combine to reduce contamination risk, costs and food waste, as well as to improve
a company’s standing in the global food industry.
